+Subject: [PATCH] Skip SDL OpenGL build check when the SDL2 wrapper is detected
+
+The wrapper does not define SDL_VIDEO_OPENGL in SDL_config.h. This
+appears to be deliberate, although it's not entirely clear why.
+
+    /* Don't define most of the SDL backends, under the assumption checking for these against the headers won't work anyhow.
+       The exception is the X11 backend; you need its define to know if you can use its syswm interface. */
+
+We could check SDL2's SDL_config.h instead, but that seems awkward to
+pull off.
+
+Closes: https://github.com/dxx-rebirth/dxx-rebirth/issues/689
